McBryde declared: "We can create a bit of history away from home. This is a young team and they know there is still plenty to fight for in the final game of this competition.
"It was a tough game last weekend but young players have no problem in getting themselves back up for it mentally. They were given a rest after the defeat to France but they had a tough training session early in the week and have got their focus back."
He said Australia have the kind of talent in their team which means they will want to run the ball against Wales.
He said: "One of the things we have hung our hat on is the fitness of the players and that is still the case. I've got no doubts in my mind that if its a running game we've got enough to last the pace.
"If we can keep the ball away form their backs and just control possession and territory we will limit their opportunities. We are aware of how many running opportunities they have behind the pack so we will try to disrupt them at source and the breakdown will again be a huge area of confrontation."
He said the chance of a third place finish in the competition will be a key incentive for the Welsh players. "We've got to make the most of these opportunities when they present themselves," he added.
"It's been a great competition for us over the lat few weeks and hopefully we can have some more success. There have been changes in our line up but I know the new boys starting for us will want to take their chance to prove themselves.
"For instance Toby has been an excellent number eight so let's see his versatility at seven . He runs great lines and he will undoubtedly have a great battle with Pocock."
McBryde praised Sam Warburton's captaincy but said Gethin Jenkins is similar in his approach and leads by example. "We won't take this game easy,"said McBryde, "It will be a great battle."
